-Be it known that-I, ADELBERT E. CARR, a citizen of the United States, residing atKodiak, intherTerritory of Alaska, have in- 5 vented a new and useful Fish oner, 'of

which the following is a specification.r My invention has reference to mechanism for removingbones fromiish, and in particular, the backbones of codish; and the objects of my invention are, to provides. cutter, cylindrical in form,` suitablymounted and connected up with power, whereby backbones'can be Vremoved from lish at alspeed heretofore 'unattained in the industry,and

atthe same time saving choice portionsof the fish which formerly have been wasted; further, vajgauge', which instantly yadapts the device for4 economicaluse withiish'of varying sizes.. l j

The out as made will .be Vin the form of a rougnd core, which, as the cuttingY progressesl vwill be automatically expelled trom t'he`di`seharge endof the pipe 3. lThis core is practically. all bone. TheY old triangu-V lar cut heretofore mentioned represented the round backbone withy the loin, the vchoicest part of :the lish'. adhering on three sides.
